What is episodic asthma?

Airway inflammation: Simplistically, asthma is characterized by airway inflammation, and falls into the classification of allergic or atopic diseases. In response to various "allergens", such as pollens, mold, dander, etc., the body creates an inflammatory response which leads to bronchoconstriction. In some, this is chronic, in others, this can be occasional or "episodic." therapy is generally straightforward.

Episodic: Asthma is now called intermittent asthma , where you only have asthma symptoms two days per week or less.

Not persistent: Episodic asthma means that asthma symptoms occur only periodically and likely triggered by exposure to an allergen ( not all asthma is from allergies) , an irritant (air pollution), a viral infection etc. Symptom-wise, most asthma sufferers have symptoms only intermittently but when lung function is measured, some degree of airway obstruction is often present even when there are no symptoms.
